The slope piece serves to control the transverse profiles of the drainage ditches and cuvettes during their construction.
It has a triangular shape and consists of three pivotally-interconnected planks; slope ( hypotenuse ), vertical with a plumb and connecting level . The slats on one side have holes that allow you to install a slatted slat with a slope equal to the design slope slope (1: 1; 1: 1.5; 1: 1.75; 1: 2).
